Description

Technical Field

[0001] The invention belongs to the technical field of motors, and relates to a test bracket for a suspended motor, in particular to a suspended motor test device capable of realizing multi-degree-of-freedom adjustment. Background Art

[0002] Motors are usually installed in a frame-suspended manner. With the development of domestic rail transit, especially the increasing number of subway lines, the interface size requirements for motors in various projects vary, and according to incomplete statistics, there are more than 40 types.

[0003] After the first batch of motors are produced, they need to be tested for motor type and ground system joint debugging. Testing is an important step in verifying whether the motor design meets the requirements. The motor type test requires 1 motor and 1 test bracket (to connect the motor and the load and fix them securely). The ground system joint debugging test requires 4 motors and 4 test brackets (to connect the motor and the load and fix them securely). Usually, motor type tests and ground system joint debugging tests use different test benches. Due to the different center heights of the load benches, different test brackets need to be configured, which further increases the types of test brackets.

[0004] The test stand needs to meet the requirements of different motor interface sizes and test load platform center height. Common interface types of frame-mounted motors are as follows: Figure 1 As shown in the figure. The mechanical installation interface is located on the upper and lower suspension. Figure 2 , Figure 3 and Figure 4 As shown, the dimensions of the upper hanging interface include a height dimension H1, a horizontal dimension L1, and an axial dimension B1, and the dimensions of the lower hanging interface include a height dimension H2, a horizontal dimension L2, and an axial dimension B2.

[0005] Prior art 1: The test bracket is limited by the upper and lower hanging installation interfaces of the motor and the upper limit of the center of the test load platform. Any change in size will make the test bracket non-universal. The test brackets are diverse in types, difficult to manage, have high manufacturing costs, and have long production cycles.

[0006] The second prior art relies on the thickness of the gasket under the block to adjust the height dimension, which is limited by the thickness of the gasket and cannot achieve smooth adjustment of the height dimension. Only the height dimension can be adjusted, and the axial and horizontal dimensions cannot be adjusted.

[0007] Therefore, as the number of motor interface types increases, the number of test brackets increases, and the cost of test brackets increases significantly. Summary of the invention
